Surgical management of pulmonary adenocarcinoma presenting as a pure ground-glass nodule

With recent advances in radiology, the detection of ground-glass nodules (GGNs) has become increasingly common. However, there still is no consensus on management, especially on the need for systemic lymph node (LN) dissection. The purpose of this study was to evaluate the surgical outcomes on the basis of the extent of resection of the primary lesion and mediastinal LN dissection and to carefully suggest appropriate treatment strategies in the patients with pulmonary adenocarcinoma presenting as pure ground-glass opacities.
